29 Murray is kind of a broad group since Murray made several bodies for Ford. The Murray and Briggs cowls were very much alike but they used a lot of wood and generally, the sub rails were also wood. The steel sub rail extensions were used on all the cars that had steel sub rails or body sill. (whatever term a person wants to use) I'm not so sure about the wood framed cars like the different fordor bodies and the cabriolet. They probably did use them but I don't know if they are exactly the same. If Ford supplied them to the sub contractors, they would most likely be the same.
